What were you hoping for? A stabilised built in laser rangefinder/Thermal Imager/MMW radar sensor built into the helmet. While supposedly better western HMS are still on drawing boards or anywhere except in aircraft these simple sights have been operational now for almost 20 years. Exactly what else would a proper HMS do that this can’t? Do you really think in the few second it take a pilot to look at and lock up an enemy aircraft his height or speed or AOA will change so drastically that he will need this information in his visual field of view?
well, I have to say I too agree. Surely, my comment on the ‘look’ of the helmet did not mean to undermine the advantage, Arsenal HMDS has provided Russian fighters in WVR arena, over the years. But for the sake of discussion, I feel new features should be incorporated to the Russian HMDS. e.g night vision, cueing of other fire control sensors, if it is not already capable of.
cheers,
